Decommissioning the Inverter

To decommission the inverter completely upon completion of its service life, proceed as described
in this Section.
Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs 84 kg (185.2 lbs). You risk injury if you lift the inverter incorrectly or if it is
dropped while being transported or mounted.
• Carry and lift the inverter in an upright position with several people without tilting it.
Requirements:
☐ A pallet must be available.
☐ Original packaging with paddings must be available.
☐ All transport handles must be in place.
Procedure:
1.
Danger to life due to high voltages
• Disconnect the inverter from all voltage sources (see Section 8, page 50).
2.
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down.
3. Remove the AC conductors from the inverter. Loosen the screws with a Torx screwdriver
(TX 30) and pull the cables out of the terminal point.
4. Remove the equipment grounding conductor of the utility grid from the equipment grounding
terminal: Loosen the screws with a Torx screwdriver (TX 25) and pull the equipment grounding
conductor out under the clip.
5. Remove all AC conductors from the inverter.
6. Remove the conduit from the enclosure opening in the AC connection unit. To do this, screw
the sleeves out of the enclosure opening from the inside.
7. When the AC surge arresters are inserted, pull the surge arresters out of the slots. To do so,
squeeze the grooved areas on the left and right sides of the surge arrester.
8. Position the enclosure lid of the AC connection unit
on the AC connection unit and first tighten the
upper-left and lower-right screws, and then the
remaining screws crosswise using a Torx screwdriver
(TX 25) (torque: 6 Nm (53 in-lb)).
